Given numbers are 644, 986, 231, 152

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 986 are 2 x 17 x 29

Prime factors of 231 are 3 x 7 x 11

Prime factors of 152 are 2 x 2 x 2 x 19

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 644, 986, 231, 152

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(644, 986) = 317492

GCD(644, 986) = ( 644 x 986 ) / 317492

= 644 / 986

= 644

Step2:

LCM(2, 231) = 462

GCD(2, 231) = ( 2 x 231 ) / 462

= 2 / 231

= 2

Step3:

LCM(1, 152) = 152

GCD(1, 152) = ( 1 x 152 ) / 152

= 1 / 152

= 1

So, Greatest Common Divisor of 644, 986, 231, 152 is 1
